Hello Amazon IoT SiteWise

The following code examples show how to get started using Amazon IoT SiteWise.

#### [ Java ]

**SDK for Java 2.x**  
 There's more on GitHub. Find the complete example and learn how to set up and run in the [Amazon Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/iotsitewise#code-examples). 

```
public class HelloSitewise {
    private static final Logger logger = LoggerFactory.getLogger(HelloSitewise.class);
    public static void main(String[] args) {
         fetchAssetModels();
    }

    /**
     * Fetches asset models using the provided {@link IoTSiteWiseAsyncClient}.
     */
    public static void fetchAssetModels() {
        IoTSiteWiseAsyncClient siteWiseAsyncClient = IoTSiteWiseAsyncClient.create();
        ListAssetModelsRequest assetModelsRequest = ListAssetModelsRequest.builder()
            .assetModelTypes(AssetModelType.ASSET_MODEL)
            .build();

        // Asynchronous paginator - process paginated results.
        ListAssetModelsPublisher listModelsPaginator = siteWiseAsyncClient.listAssetModelsPaginator(assetModelsRequest);
        CompletableFuture<Void> future = listModelsPaginator.subscribe(response -> {
            response.assetModelSummaries().forEach(assetSummary ->
                logger.info("Asset Model Name: {} ", assetSummary.name())
            );
        });

        // Wait for the asynchronous operation to complete
        future.join();
